Abstract
Abstract A wire or similar elongated element of metallic material is advanced between at least one pressure roller and at least one counter-roller and is engaged with the pressure roller under pressure to be rollingly deformed; the pressure roller may be profiled to form ribs, grooves or the like on the wire. The pressure acting from the wire on the roller frequently reaches such a force that it tends to destroy the pressure roller, and in accordance with the invention a counter-force is exerted upon the roller, to compensate for the force acting on the same from the wire so as to prevent its destruction.

Claims Analysis
Total Claims: 29
Claim 1
Independent Claim
77 words
In a method of rollingly deforming elongated blanks by advancing the same between a pressure roller and a counter roller while subjecting the same to pressure, whereby the pressure roller is subjected to the action of forces having components acting in the axial direction of said pressure roller, the improvement which consists in hydraulically subjecting said pressure roller to axial compression of such magnitude as to counteract said components at least while the rollers deform the blanks.
Claim 2
Dependent Claim
77 words
In a method of rollingly deforming elongated blanks by advancing the same between a pressure roller and a counter roller while subjecting the same to pressure, whereby the pressure roller is subjected to the action of forces having components acting in the axial direction of said pressure roller, the improvement which consists in hydraulically subjecting said pressure roller to axial compression of such magnitude as to counteract said components at least while the rollers deform the blanks.
Claim 3
Dependent Claim
94 words
In an apparatus for rollingly deforming elongated blanks, a combination comprising a shaft; a pressure roller having a circumferential surface adapted to engage and rollingly deform the blanks, whereby said roller is subjected to the action of first forces having components acting in the axial direction of said rollers; and a hydraulically actuated cylinder-and-piston unit having a cylinder member and a piston member, one of said members acting upon said pressure roller adjacent said circumferential surface so as to exert upon said pressure roller second forces counteracting said axial components of said first forces.
Claim 4
Dependent Claim
94 words
